MBAM 2.5 - Encryption on battery power

Hello,
I have recently deployed MBAM 2.5 and have configured the client to silently encrypt. This works perfectly when on AC power (big thumbs up), but this process fails when the laptop is on battery power. Is there any way to override this rstriction ?
In our scenario, the laptops will never be used on AC power as they are charged in storage trollies, and also will contain no user data (encryption as a best practice) - so I am not concerned for potentially broken installation, or loss of data etc.

Yes of course you can pre-provision bitlocker during OSD through SCCM or MDT.
But I don't think that after the installation of agent and the GPO applied it takes a longer time. It will be a matter of 1-2 minutes only.
But if you want to pre-provision then check out this link:- Using MBAM to start BitLocker Encryption in a Task Sequence

Macbook airport problems linked to battery power?

I too have experienced the macbook/airport problem, specifically since 10.5.8 came back. When I upgraded to 10.5.8, it was so useless that I just reinstalled tiger. Then Snow leopard came out and I upgraded only to experience the same problem but not as severe.
I have just been able to pin/point the problem today (mainly because I just grew so frustrated and spent considerable time trying to figure out). I have tried all the other potential fixes posted on here to no avail (changes airport settings, replacing card, changing dynamic IP to manual, encryption etc).
This is what I have determined and was able to reproduce it:
When macbook is running on power (plugged in):
If battery power is below 60%, connection is spotty - the lower it is, the worst the problem.
If the battery power is above 60%, no problems at all, runs fast and no drops.
When macbook power is not plugged in and running on battery:
Below 60% almost useless
Above 60% spotty and worse as the battery drains
Can anyone else test this out? I've sent Apple an e-mail.

I've gone down to maybe 15% without any noticable difference in connection.

MBP running out of battery power before sleeping - Help!

Hi
My MacBook Pro has been running out of battery power before the memory-saving sleep mode kicks in, so it dies with a little click of the HD. It's not a hibernation state as when I reattach the power supply it boots up a new session.
I've noticed this since upgrading to Snow Leopard last year, but put it down to an old battery that had 45% charge and wasn't powering the MBP properly. I now have a replacement A1175 5600mAh battery which is giving me 2-3hrs usage (which I'm pleased at), but now it still dies before sleeping!
I have tried to cycle the new battery, but can't. I have reset the SMC several times, with no effect.
I used to cycle the battery every week or two, running it down until it would no longer wake from sleep, recharge overnight etc, but now I can't do this because it will die before sleeping!
I've read quite a few articles over the net about this issue, but there seems like no cure. It's really annoying me now as I frequently work on the move and a dying MBP could potentially be disastrous.
Can anyone shed some light on this issue? Is there something I haven't tried yet? I think it's a late '06 MBP.

If you are not getting a warning, then there is something amiss with your battery. If a SMC reset and calibration does not fix the problem, then you may need to make an appointment at the genius bar and arrange to have your battery tested.
My old battery started doing the same thing--shutting down without warning. I replaced it, and the replacement battery started doing the exact same thing. I then returned the replacement, and the next replacement battery behaves in a normal fashion.
My first battery was worn out. My second battery was defective. My third battery is good.
Your battery should still be under warranty. Go back to where you got it and show them what it is doing and see if you can get a replacement.
Good luck!

MBP (13-inch, early 2011) goes into hibernation instead of safe sleep upon closing the lid (only when using battery power)

MBP details
13-inch MacBook Pro, early 2011 (model identifier: MacBookPro8,1)
Running Yosemite, OS X 10.10.1 (however, problem started while using Mavericks)
2.5 GHz Intel Core i5
4 GB memory
Symptoms
* the MBP goes into hibernation instead of sleep upon closing the lid on battery power (i.e., when AC adapter is NOT connected)
-- problem does not occur when AC adapter is connected
* putting the computer to sleep by other means does not induce the problem; these other means include:
-- [i] option+command+Power,
-- [ii] Apple Icon --> Sleep,
-- [iii] in Terminal: pmset sleepnow
* the battery is NOT getting drained at all; if I close the lid on 87%, the battery is still at about 87% when I get the MBP back up and running
To be as clear as possible:
(1) MBP is on and in use (power source: battery); battery is at X%
(2) the lid is then closed
(3) the battery indicator light glows bright for about 10 seconds, then shuts off, and with it so does the MBP (all fans and sounds cease)
(4) opening the lid and pressing any key on the keyboard does nothing (the computer is not sleeping)
(5) to turn the MBP back on, I must hit the power button once; this brings up and the gray screen and loading bar indicative of returning from hibernation
(6) log in; battery is still at X%
Attempted Solutions / Fixes
There are Apple Discussions addressing similar MBP issues, many of which at least have work-arounds, if not full-blown solutions. However, I have tried many of the proposed work-arounds and solutions; nothing has solved my problem. Such attempted solutions include:
* made sure EFI/SMC firmware was up to date
* updated all software
* logged in as a different user
* booted in Safe Mode
* reset the PRAM
* repaired disk permissions using Disk Utility
* repaired additional disk permissions in recovery mode (a la this chron.com advice)
* ran the Apple Hardware Test multiple times (short test while plugged in, short test on battery, extended test while plugged in, extended test on battery)
* booted from an external known-good OS on USB drive
* reseated the RAM
* used MemTest to test the RAM's health (it was good)
* tested my battery's health with the app Battery Health (it is healthy!)
* booted my computer with one stick of the MBP's original RAM at a time (figured "why not?")
* booted my computer using other sticks of RAM
* checked my power management settings using PMSET in the terminal (e.g., pmset -g); tried various hibernation modes (e.g., sudo pmset -a hibernationmode X, where X=0,1,3, etc)
* searched/grepped through my power management logs and Console messages to look for googleable items (e.g., pmset -g log | grep WORD, where WORD=failure, sleep, etc); still have not found help online
* brought the MBP to a Mac Genius
-- he ran some further tests, but found nothing;
-- he re-installed my OS as a hopeful-hail-mary-just-maybe-last-ditch effort; the problem persisted!
-- we both agreed that we had ruled out a software cause
-- he offered me to leave my MBP to get fixed for a flat fee of $300.00 (which after a couple weeks of trying to figure this out is starting to sound more and more reasonable)
Given that it is likely not a software issue, what hardware might it be? By booting from an OS on an external drive, I think I've ruled out a bad hard drive or hard drive cable. Also, given that inducing sleep in any way other than closing the MBP's lid does not cause the problem, it seems there might be a wire (or something) in the hinge section of the MBP that gets moved when the lid is closed possibly causing some kind of short circuit...or something.
If someone with more experience interpreting Console messages, for example, can help, I'd be happy to provide some logs, or any additional information.
Thank you for your time and consideration.

Ok, this is a crazy-simple, quasi-embarrassing fix, but I'll post it anyway just in case anyone is having a similar problem (for example, this guy: Changes to pmset being ignored).
Some time around late last August / early September (2014) this issue began happening for me (specifically, issue = closing lid while on battery power induces hibernation / shut down instead of sleep --- independent of hibernation mode). Maybe it was when I upgraded to Yosemite (not sure what the exact date of that was). As detailed in my original post, I frantically tried everything I could think of... At that time, however, I had quite a few presentations and posters to create and present at meetings and conferences, so I held off fixing it for a couple of months and returned to it this past week, where I tried a few more things listed above, but again to no avail...
This morning, I simply tried fudging around with all my power management settings again (via pmset in Terminal). The simplicity of the fix surprised me. But now that I understand it, I know it is likely the same fix for other threads I've read, such as the one above:
(TLDR in bold)
(1) Take note of your power management settings (Terminal: pmset -g custom)
(2) Is the "standby" flag set to 0? If so, set it to 1. Wa-la! Done.
This fix is crazy and embarrassing b/c I was so close to it for so long. I tried changing my hibernation modes multiple times (sudo pmset -a hibernatemode X, where X=0,1,3,25,etc). I read about manipulating other PMSET settings that helped other people with newer MBPs, like "autopoweroff" and "autopoweroffdelay" --- settings that I do not have on the MBP early 2011 (check your settings: pmset -g cap). And most amazingly of all, I even messed with the "standbydelay" setting, trying to make it so long that my computer should never go into hibernation... Yet, from what I can tell by looking over my notes, I never simply set "standby" from 0 to 1.
There are interesting questions that arise due to this fix. For example, why did this problem persist on clean installs of OS Yosemite? Is "standby" being set to 0 the Yosemite default? I'm not sure. If it is, then Kappy was right: this was normal behavior... It just wasn't always the normal behavior...at least not for my MBP. Normal behavior (hibernatemode 3) used to be (and now is again) that the MBP goes into safe sleep, and then only after an allotted amount of time will it go into full-blown hibernation.
NOTE: the "standby" and "standbydelay" PMSET settings are not available in some earlier MBP models (e.g., my brother has a 2010 and does not have these settings); so if you're having a similar problem with an earlier model, this fix might not be of any help to you.

Mac Book Pro Shuts down on Battery Power

First, I apologize to everyone for asking this question yet again. I have gone through the previous posts and I am still at a loss. So thank you for your patience and help.
When I run my MacBook pro on battery power it will run for around 15 - 20 minutes... then just be dead. No low battery warning. No shut down. Just poof and gone.
I have looked at my power settings to see if my battery is bad. But I don't have a Status indicator in there. I see This:

I have also looked at the directions on http://support.apple.com/kb/ht1490 about how to calibrate my battery. It says:
" 1. Plug in the power adapter and fully charge your PowerBook's battery until the light ring or LED on the power adapter plug changes to green and the onscreen meter in the menu bar indicates that the battery is fully charged.
2. Allow the battery to rest in the fully charged state for at least two hours. You may use your computer during this time as long as the adapter is plugged in.
3. Disconnect the power adapter while the computer still on and start running the computer off battery power. You may use your computer during this time. When your battery gets low, the low battery warning dialog appears on the screen.
4. At this point, save your work. Continue to use your computer; when the battery gets very low, the computer will automatically go to sleep.
5. Turn off the computer or allow it to sleep for five hours or more.
6. Connect the power adapter and leave it connected until the battery is fully charged again."
Only I have a problem withe step 3 and 4. I don't get the warning, and it doesn't go to sleep. So, I don't think any calibration is working.
Do I need a new battery? Should I just buy one? This computer is WAY out of warranty and I never purchased and apple care plan for it.
Again, than you for any and all advice on what I may need to do.

I think it's time to buy a new battery

MacBook Pro C2D shuts down instead of going to sleep (on battery power)

dear macusers,
it happended the first time 2 days ago, today again: while my MacBook Pro is inactive on battery power the screen dims, then turns black like usually, but then it doesn't go to sleep, instead it shuts down. I have 10.4.8 installed, i didn't do the summertime update. I took a look at the log files (/var/log) but couldn't find something strange. Never had a problem using my machine...
anybody has the same issue?
sorry for my bad english!
john

When that happened to me a couple months ago with my Powerbook G4 it happened to be the battery itself. I did the apple battery exchange since there was a recall on my battery. I use my notebook primarily as a desktop replacement and hadn't noticed the problem until months later when I unplugged the notebook, seconds later the notebook would shutdown and even reset the system clock.
Applecare couldn't figure it out so I went to my friends house and swapped batteries to test and sure enough, when I put my battery into his computer, it shut his down and reset his clock.
Check the battery.

HT201263 When my Ipod touch is in autolock I can only restart the device holding the sleep/wake button and home button at the same time for 10 seconds. While in auto-lock it is using battery power and will do so until the battery is drained. Whats wrong

When my Ipod touch is in autolock I can only restart the device holding the sleep/wake button and home button at the same time for 10 seconds. While in auto-lock it is using battery power and will do so until the battery is drained. Whats wrong?

- Try a reset. Nothing is lost:
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears
- Connect the iPod to your computer and try to restore via iTunes. Try placing in Recovery mode if necessary to restore.
- If you can't turn the iPod completely off, let the batter fully drain. After charging for at lerast anhour try again
- If still not successful time for an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

How can i use an external screen on mountain lion when i'm running on battery power?

Hey all:
I just upgraded from snow leopard to Mountain Lion, and i use external screen, keyboard and mouse all the time....
On Mountain Lion it's perfect when the power adaptor is connected as soon as you close the LID your external screen becomes the primary screeen and it's fully functional desktop (no mirroring or extension screen)
But the problem is when i'm in battery power, in snow leopard i used to close my lid my mac goes to sleep then i wake it up using the mouse and immediately open the LID so it doesn't go to sleep again and now i'm running on battery power with a primary external screen.
Any idea how to use an external screen on mountain lion while i'm on battery power? (i know i can use mirroring but i want just 1 primary screen and the laptop screen would be turned off )
Thanks for the help.....

You can't with the lid closed, that's one of the rules for clamshell mode.

Laptop freezes while on battery power.

I have Arch 64 bit install on a Thinkpad T510. While the laptop is plugged into power, it is rock solid and can run for days without a crash.
The laptop freezes up quite often when it is running on battery power. After anything from 15 minutes to an hour, it will probably freeze. I cannot switch to a tty, I just have to do a hard reset.

I'm not sure if tracker could be causing the problem, or if it is something else.
I have the discrete graphics card enabled - NVIDIA Corporation GT218 [NVS 3100M]

It might not necessarily be caused by loss of power, but maybe if the battery power dips? Or if the battery gets too hot and something overheats, then that could cause freezing. I'm only going by what I've found on google.
Anyway, I found another thread (not sure why I didn't see it before) that suggests that it might be caused by bluetooth (bluez specifically) https://bbs.archlinux.org/viewtopic.php?id=115814, but it seems like that was more of a locking up problem than freezing completely. I've remove bluez and disabled bluetooth for now anyway (unfortunately can't remove it completely because I'm on Gnome Shell) and I'll run on battery for a good while and see if things freeze again.
EDIT: also followed this - https://wiki.archlinux.org/index.php/HDAPS in case the problem was caused by the hard drive being moved about.

Battery, Power, Deep Sleep and Spotlight problems after 10.9.4 update

Hi, I have a Macbook Pro 8,1 13in (Late 2011). I updated to the latest version of Mavericks (10.9.4) and iTunes on Sunday, right after that my macbook started to goes into Deep Sleep after closing the lid, even when the battery was 80% of charge. My battery normally lasts for almost 5 hours. After it went to deep sleep, the power bottom does not respond. Also, I have noticed that spotlight process in Monitor was consuming so huge amount of resources. This problem persists in Boot Camp. There is no way to turn the machine up without plugging it to the power cord. Sometimes it charges the battery as usual, sometimes it does not recognize the battery. Suddenly, the mac goes into sleep mode while I'm using it.
I have researching and troubleshooting in order to fix this but no solution. I have reset the PRAM and SMC. I made a backup of my files and installed Mavericks from the ground with external storage in order to erase the entire disk, no solution. I made an Internet Recovery and downgraded it to Lion, it worked for 2 hours and then I upgraded again to Mavericks (10.9.0) and the same problem came again, the upgraded to 10.9.4 and no solution at all.
I have searched on internet and there are other people experiencing this problem but nobody is able to bring a valid solution.
This is my battery's health:

Reseting the NVRAM/PRAM doesn't solve my problems.
Hi, since you have performed NVRAM /PRAM reset, try:

W520: How to get full speed and turbo on battery power

Here is how you get around the on battery max frequency limitation (of 1.2 GHz, at least for my i7-2620M) and no turbo (well, almost, read on):
0. Assuming you have max performance enabled everywhere possible (BIOS/PowerManager/Windows Power Scheme)
1. Load ThrottleStop.
2. Set the multiplier manually to your maximum multiplier (e.g., 27x for i7-2620M, 23x for i7-2820QM, etc...) or Turbo (which is the setting after your max multiplier).
3a. Enable ThrottleStop
3b. (optional) Check in CPU-Z and make sure that your highest multiplier is being used when the CPU is utilized. If you selected Turbo, you should have turbo enabled at this point.
4. Disable ThrottleStop
5. Exit ThrottleStop, so that it doesn't waste any battery power, since it is no longer needed
This will change the max frequency (and max multiplier) available from whatever Lenovo decided to arbitrarily fix it at (e.g., 1.2GHz) to the correct max frequency (which in my case is 2.7 GHz / 3.2 GHz for turbo). Now your laptop will be able to correctly go from 800MHz to whatever is the max frequency of your CPU, using both EIST and C1E. Turbo will also kick in, if you enabled it in ThrottleStop and the Lenovo PowerManager app will even show it as enabled.
Thanks Unclewebb for letting us get around this stupid max CPU frequency limitation that Lenovo has imposed on us.
Disclaimer:
Do this at your own risk, since Lenovo does not officially support it.
Turn on active cooling, if you do CPU intensive stuff for any prolonged period of time. This will take away some on battery time, but if battery time is of ultimate concern to you, then this change is probably not for you to begin with.
If you go through prolonged periods of CPU intensive activity, you will lower your battery life and produce a lot of battery heat, because you will have a relatively high discharge rate. A high discharge rate reduces both the number of charge cycles and the maximum charge capacity of a Li-Ion battery. I don't know how safe all of this is, so do this at your own risk and probably monitor temperatures along the way. Other laptops can do Turbo and full speed on battery power (e.g., the slim 3 lb Sony Z, with the i7-2620M), but then other laptops have different designs and cooling systems, so who knows how the Lenovo W520 hardware will react to this.

Hi,
I have the opposite problem - my i7-2720QM is fixed at 2.2GHz no matter how hard I spank 1, 2 or all cores, and no matter what System Performance settings I apply. It even runs at this speed, and gives the same bench marks when on battery with the "system performance" set to Low.
No one even knows what the various System Performance settings actuall mean. E.g. Neither Lenvo support nor these forums could tell me what the difference between "Maximum Turbo","Turbo" or even "Low" under "System Performance" in the Lenovo power manager Advanced settings.
I have been trying go get turbo boost to work for 2 months. I have wasted so much time with this machine, I could have bought 2 Macbook pros for the cost of the time lost.
I dont know why Lenovo have disabled the turbo boost (and the opposite, turbo drop?) feature for this CPU - is it deliberate, or incompetence? Its certainly false marketing and extremely annoying that I have to use my ancient PC to do single threaded type work which I know the Laptop can manage if it were not crippled.
So people whos clock speed drops when on battery are the lucky ones. Mone doesnt even if I want it to.

Battery power and redundant shutdown while syncing

This is mostly a suggestion for the folks at apple, but it seems that you can't just E-mail them these days.
When an iPod's battery is low and you plug it in to sync, often times it gets partially through the syncing process and then decides that it doesn't have any power to continue. So, it shuts itself down leaving you with an incomplete sync that restarts all over again when you plug the iPod in.
This is ESPECIALLY problematic when you are the situation that I am in- the one that made me come here and learn how to use discussions -restoring your iPod. I was having a few little errors in the use of my iPod. Nothing serious, mostly just that the artwork was messed up (on the iPod, and not in iTunes). So I figured 'what the heck, restore it, can't do any harm'. I plug the iPod in, hit restore and PRESTO! Beep beep, beep beep, beep beep. The iPod redundantly shut itself down saying that it didn't have enough battery power, rendering all the files that HAD loaded, useless, because the next time you try to sync it starts over from ground zero.
The iPod should be able to charge and sync at the same time. In the event that this is impossible, then the iPod should be able to say to itself "Bob, you're going to die if you keep syncing. Let's take a break and spend some time charging up the old battery." Rather than saying "Bob, you're going to die if you keep syncing. Why don't you just do that, waste the owner's time, and make the world one redundant iPod angrier."
Does anyone else have this problem? Does anyone else agree? or am I just being stupid about the whole thing?

you might try setting the processor performance to reduced
might also try checking the Activity Monitor to see if there is a run away process.

Before I upgraded my iPad mini, you could turn off apps to save battery power by double clicking the control button and then holding your finger on the app button until the minus sign appeared. That doesn't work anymore. How do you turn off the apps wit

Before I upgraded my iPad mini, you could turn off apps to save battery power by double clicking the control button and then holding your finger on the app button until the minus sign appeared. That doesn't work anymore. How do you turn off the apps with ios7

Now you swipe downward, the app will appear and you delete, keep scolling to the right as in the past. With the new operating system you also swipe downward to get the search bar to find an app

BlackBerry PlayBook battery power charge, discharge characteristics, and guidance on extending battery life
KB27705
Overview
The BlackBerry PlayBook may come to a power state where it is unable to power on; a Yellow LED may flash in a sequence of 5 flashes, the BlackBerry PlayBook may boot up to the BlackBerry PlayBook Logo and then power off, may not power on at all.
Discharge behavior under normal use:
Under normal active use, a battery drained to 10% will cause the device to prompt the BlackBerry PlayBook user (notification and audible beep)
Without connecting a charger the device will automatically shut down at 3.53V (0%)
Pressing the power button may allow successful boot, but it will turn off again very quickly
Discharge behavior under no use:
A device left unused but in ‘Stand By’ will warn the BlackBerry PlayBook user at 10% (notification and audible beep)
The warning may not be noticed and the device will go back to ‘Stand By’
Letting the device drain in standby mode drains the battery slower, but more completely
Device will still shut off at 3.53V (0%), but it less likely to successfully boot afterwards
Discharge behavior under 3.53V (0%):
If the device is left to shutoff, the battery will continue to drain below 3.53V due to quiescent current draw from the motherboard and the battery fuel gauge
With the battery between 2.7V-3.53V, pressing the power button causes the LED to flash a pattern (1 solid red light followed by 5 yellow blinks) to indicate low battery (PlayBook Tablet OS version 1.0.5, and above)
Below 2.7V there is no activity, or LED pattern displayed
Charge Behaviour:
The provided charger should be used to charge the device. The optional 12 volt rapid charger is may reduce charging times
to approximately 3 to 4 hrs. Standard Blackberry smartphone chargers, other AC adapter USB chargers, or computer USB ports
are not recommended for the sole purpose of charging the PlayBook as with these methods it may take more that 12 hours to
charge the BlackBerry Playbook.
If the battery voltage is below 3.53V(0%) then the charging behaviour is dependent on the software version. The charging code will limit the charging current to under 400 milliamps, during which time, it may take an hour to reach 3.53 Volts. Once the battery voltage rises past 3.53 volts, then "high-rate" charging will start. If, after charging the Tablet for 4 to 6 hours still does not result in LED activity, attempt to force power on the BlackBerry Playbook by pressing and holding only the Power Button for only 20 seconds.
Prior to BlackBerry Tablet OS 1.0.5:
A BlackBerry PlayBook will never charge while powered off in BlackBerry Tablet OS versions prior to 1.0.5.
The device will show a red light when the charger is connected and then nothing more
Repeated connection of the charger can recover the device in some instances.
Once the battery voltage rises above 3.53V the system will boot and the UI will show charging
Starting in BlackBerry Tablet OS 1.0.5:
The device will show a solid red LED, followed by a solid yellow LED as the device boots into charging mode. This is followed by a yellow pulsating LED indicating charging in progress.
The time span between the red and yellow lights can be as long as 45 seconds as the device boots into charging mode.
Once the yellow LED illuminates, the device can be started, but it is advisable to let it charge for at least 3.5 hours to achieve a sufficient charge.
The device will show a solid green LED once the device is fully charged.
Starting in BlackBerry Tablet OS 2.0.1:
Once the yellow LED begins pulsating indicating charging mode, if the BlackBerry PlayBook is disconnected from the charger, the following graphic will be displayed on the screen, indicating charging is not complete, and to reconnect the power source. The graphic will be displayed for 20 seconds before the BlackBerry® PlayBook powers off if the power source is not reconnected. The same graphic will also be displayed if the BlackBerry PlayBook is turned on and there is not sufficient power to perform the boot process.
If the BlackBerry PlayBook is plugged into a power source, and the power button is pressed to power on the device, the following graphic will be displayed if there is not sufficient power to perform the boot process. If this occurs, the BlackBerry PlayBook should be left plugged in to gain enough charge to boot.
Additional Information

With the upgrade to PlayBook OS 2.1.0.1032 the following message may be displayed when connecting the Playbook to a PC using the micro-USB cable:
Unable to charge battery with connected source
This message is displayed because the voltage provided is insufficient for charging. The USB voltage is limited to 384mA even if the maximum tolerance is 500mA. The voltage is limited to 384mA by design to avoid violating the USB specification which states USB devices cannot draw more than 500mA from the USB port.

Macbook pro and Thunderbolt display on battery power no go.

I use my macbook pro mainly on my desk with the thunderbolt display and its lid closed. While having the power adapter connected to the macbook everything works fine. When I disconnect the power adaptor and try to wake up the computer it comes to life for a few seconds and then goes back to sleep for good. I cannot use the thunderbolt display while having the macbook on battery power. That causes the issue of the battery not discharging which I am aware is pretty bad. Any advice is welcome. Thanks.

I kind of figured this out. The reason I wasn't satisfied was that without the power adaptor when you hit a button on the keyboard the monitor actually wakes up the computer, works fine for a few seconds and then puts the computer to sleep. That kind of proves that it does work, technically at least. The problem is going into sleep mode afterwards.
Anyway i guess it just doesnt work. Thanks.
ps. If there is a way of discharging the battery with software while the power adaptor was still on, would be great help.
